BRS

Tending a reef aquarium requires a lot of care and attention. The water chemistry must always be just right to allow the fish, corals, and other marine life to thrive inside the tank. Proper maintenance of your aquarium requires balancing the calcium and alkalinity levels by using several additives like calcium, magnesium and carbonate.

Bulk Reef Supply created our own line of BRS Bulk additives to maintain calcium and alkalinity with the desire to produce the highest quality products with exceptional results at affordable prices. Our Calcium Chloride, Magnesium Chloride and Sulfate, Kalkwasser, and Sodium Bicarbonate are all made with high purity, pharmaceutical grade material and come in a variety of sizes.

This can be simpler and more effective by installing tank accessories, like dosing pumps, to properly regulate the amount of calcium chloride, magnesium chloride, and magnesium sulfate that will be injected into the water. This way, every dose is consistent with the last, thus making it easier to keep track and adjust if need be.
It is also essential that you check your calcium levels every now and then since not all tanks share the same required dosage. Make sure that you balance the level based on the size of your aquarium, the amount of corals, and the number of inhabitants within.
